1 Corinthians 11 v 7-9


1 Corinthians 11:7-9 
(7)  For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man. 
(8)  For the man is not of the woman; but the woman of the man. 
(9)  Neither was the man created for the woman; but the woman for the man. 


11:7-9. The man, on the other hand, was not to have his head covered because he was the image and glory of God. Paul based this conclusion on Genesis 1:26-27. A woman’s (a wife’s) glory and image was derived from (1 Cor. 11:8) and complementary to (v. 9) that of the man (her husband). Man, then, was God’s authoritative representative who found in woman a divinely made ally in fulfilling this role (Gen. 2:18-24). In this sense she as a wife is the glory of man, her husband. If a married woman abandoned this complementary role, she also abandoned her glory, and for Paul an uncovered woman’s head gave symbolic expression to that spirit.
